Number of HCl Molecules in a Solution
To determine the number of HCl molecules present in a given volume of a solution, we need to consider the concentration of the solution and Avogadro's number.
Avogadro's Number:
Avogadro's number, denoted as NA, is a fundamental constant representing the number of atoms or molecules in one mole of a substance. Its approximate value is 6.022 x 10^23 mol^-1. This means that one mole of any substance contains 6.022 x 10^23 particles.
Concentration of the Solution:
The concentration of a solution is a measure of the amount of solute present in a given volume of the solution. It is usually expressed in moles per liter (M) or moles per milliliter (mol/L or M).
Calculating the Number of HCl Molecules:
To calculate the number of HCl molecules present in a solution, we can follow these steps:
Step 1: Convert the given volume of the solution into liters.
- In this case, we have 10 mL of the solution, which is equivalent to 0.01 L.
Step 2: Calculate the number of moles of HCl using the concentration and volume of the solution.
- The given concentration is 0.1 M, which means that there are 0.1 moles of HCl in 1 liter of the solution.
- Therefore, in 0.01 L of the solution, the number of moles of HCl is 0.1 x 0.01 = 0.001 moles.
Step 3: Convert the number of moles of HCl into the number of molecules.
- Multiply the number of moles by Avogadro's number (6.022 x 10^23 molecules/mol) to obtain the number of molecules.
- In this case, the number of HCl molecules is 0.001 x 6.022 x 10^23 = 6.022 x 10^20 molecules.
Therefore, there are approximately 6.022 x 10^20 HCl molecules present in 10 mL of a 0.1 M HCl solution.
Summary:
- To calculate the number of HCl molecules in a solution, we need to know the concentration of the solution and the volume of the solution.
- Convert the volume of the solution into liters.
- Calculate the number of moles of HCl using the concentration and volume of the solution.
- Convert the moles into the number of molecules by multiplying by Avogadro's number.
- The final result gives the number of HCl molecules present in the given volume of the solution.
